T0 @ZZ whom it may concern.'

Be it known that I, HENRY Il. HYLAND, a citizen of the United States,residing at Pittsburg, in the coun ty of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inPetroleuin-Burners and Steam-Gen craters; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

In usin petroleum and other hydrocarbons as a fuel for industrialpurposes-si'lch as the generation of steam and the heating of furnacesof all kinds-in a cheap and economical manner it is necessary to takeinto consideration the facts that the fuel must be und er perfectcontrol at all times, so that the operator can regulate the amount ofheat supplied to the boiler or other furnace; that the liquid fuel mustbe transformed into a Vapor or gas before burning, as it will in thatshape be so agitated or atomized that an approximately perfectcombustion results; that the flow of oil to the agitator or vaporizermust be steady and equal, so that the heat generated will at no timevary unless desired by the operator; that the initial heatingl andsteamgenerating must be derived from the same fuel as is used to keep upthe continuous heat in the furnace, and that the parts to accomplish thelast named result must have some function in the operation of theapparatus other than that of Vinitial heating and steam-generating, sothat l there will be no superfluous or unnecessary parts in the deviceafter the fire has been started.

The object of my invention is to embody in an apparatus elements andcombinations of elements of such a character that all the conditionsaforementioned will have a place in said apparatus and perform all thefunctions required thereof in a simple and economical manner and withoutdanger to the workman and the surrounding property.

The invention therefore consists of constructions and combinations, allas will hereinafter be described and claimed, reference being had to theaccompanying drawings, in which- Figure l represents a longitudinalsection of a boiler with my apparatus attached thereto; Fig. 2, aperspective of the initial steamgenerator, which can also be used as asuperheater; Fig. 3, a longitudinal section of the injector, and Fig. fla transverse section through the oil' and mixing chamber of theinjector.

In the drawings my apparatus is shown attached to a locomotive-furnace;but it is obvious that it can be applied to any other form of furnace,whether for generating steam or metallurgical purposes. The pipes arearranged diagrainmatically in Fig. 1 to show their connections; but inpractice I shall arrange them in accordance with. the construction towhich they are attached, an d will malte such chan as the nature of theconstructions may require.

A represents the boiler 5 A', the lire-box; A2, the dome; A3, the cabhaving the floor A4, and A5 the initial heating and steam-generatingdevice. The part A5 is arranged in the fireboX in any suitable manner,but preferably rests upon the dead-plates of the grates. It is formed ofan outside coil of pipes, a, and a series of smaller pipes, a', arrangedin any suitable manner, preferably in the manner shown-that is, a numberof pipes arranged in horizontal rows and joined together at their endsby elbows and each alternate row having its pipe opposite the pipes ofthe other row, so that the heat will pass around all the pipes inclosedby the large pipes o, and each row is connected by one end to the rowbelow it and by the other end to the row above it, and the lowermost rowis connected to the lower coil of pipes, a, The top row is provided witha pipe, a2, which connects with a steam-drum, A6.

The lower coil of pipes, a, is connected by a pipe, o3, with awater-reservoir, A7, that receives its supply from any suitable source,and is shown in this instance connected by pipes a4 and a5 with thewater-space of the boiler. Pipe a5 is provided with a cock, a6,

cutting off the supply when desired. Apipe, a7, leads from the drum A6to an injector, B, located at the doorway of the fire-box, and which Iwill now describe.

B represents a casting having an annular chamber or oil-space, o, anozzle, b', having a IOO passage, b2, opening at its rear end into aconoidal chamber, D?, into which projects a series of conoidal nozzles,h4, pointing to a common center, as shown in Fig. 4;, and separated attheir extreme ends lf a sufficient distance to permit a blast of steamto pass opposite to apertures or openings in. the apices of saidconoidal nozzles. c The rear ends of these co- .noidal nozzles open intothe oil-chamber h, and are provided with valves b, cach having a needle,127, for keeping the apertures of the nozzles clear, and a stem, bs,having a bandwheel, b, and screw-threads which engage with thescrew-threads formed in the hollow plug bw. This plug has screw-threadson its outer surface to engage with the screw-threads of the openings U2in the outer wall of the oil-chamber. A screw-cup, bw, is also screwedover the end of the plug, which extends outside of the oil-chamber toprevent seepage of the oil. In the rear end of the conoidal chamber b3 aspider, b1, is screwed. This spideris provided with a central openi ng,partly screwthreaded, for the steam-nozzles bl, which extend throughsaid opening to a point near the ends b5 of the nozzle l1" and in thesame plane as the common center to which they point. The rear part ofthe nozzle is partly inclosed by a perforated tube, hl, secured by oneend in the casting B, and provided with a cap, t, screwed upon its rearend. rlhe rear .end of the steam-nozzle is provided with a tie-coupling,to one end of which is secured the pipe al, leading from the drum, andto the end a pipe, a8, leading to the steam-dome. This pipe is connectedwith pipe a by a pipe, a9, provided with a cock, am. rIhe pipes al andas are respectively provided with cooks a'12 and am. From pipe as asmall pipe, a, leads to a steam-space, 618, formed by the cap 519,secured to the said nozzle. Oil is'supplied .to the chamber b3 by apipe, C, connected ,with a suitable reservoir and havin gabranch pipe,C,which leads to the initial steam-heating device A.

The operation of the device is as follows: The cocks in pipe a4 areturned to admit water into the reservoir A7, and pass from there intothe part A5. When a sufficient quantity has passed, the water is cutoff, the cocks in the oil-pipes turned to admit oil into the branch C',and ignited to heat waterin pipes a. The steam generated in thelatterpasses through pipe a2 to steam-drum A6. After a sufficientquantity of steam is supplied to drum A, the cock in pipe in al isturned to admit the steam into the injector B, and the cock in oil-pipeC is turned to admit oil into chamber b3, and passes through the nozzlesh4 Ain line jets, which are impacted upon by the blast of steam andatomized. The force of the blast also draws air through the perforatedtube and the spaces in the spider, and the steam, oil, and air arethoroughly mixed lin the chamber b3 and projected into the .fire-boxthrough passages h2, where it is subjected to cross-currents of steamfrom the steam-space Z218 before it enters the furnace. As soon as theboiler has generated steam of sufficient pressure, the oil-pipe C isclosed and the supply of steam from drum A6 is cnt off, as steam can nowbe supplied to the injector B through the pipe as. If it be desired tosuperheat the steam passed to the injector B, the water is withdrawnVfrom parts A5 and AVT by opening the waste-pipe AS and allowing thewater to escape. The wastepipe is then closed and cock al in pipe a9 andcock al? in pipe al opened. Steam from the dome will now pass throughpipe a, drum AT, pipe ai), part A, pipe a2, drum A, and pipe a" to theinjector B, as well as directly through the pipe as to the injector B.rlhe heat in the fire-box will soon superheat the steam passing throughpart A5, and as soon as it is accomplished cock as is closed and all thesteam supplied to the injector B must pass through the part A5 before itis used. By these means I am enabled in a few minutes to start andmaintain a lire of sufficient power to supply the initial heat necessaryto heat the boiler to the point at which it will give ol'f steam. ofsufficient pressure to vaporize the oil without the use of other fuel,and this may be accomplished at any time and as often as desired.` Thisis a very important factor in using petroleum as a fuel. It obviates thenecessity of providing other fuel and at the same time does notinterfere with the proper disposition of the other parts of theapparatus. On the contrary, the device used forms an auxiliary which canbe utilized as a superheater without any changes more than the changingof the position of a few cocks.

To pre vent the pipes from burning out when the steam-generator is usedas a superheater, I provide an asbestus curtain or shield, D,

(shown in dotted lines, Fig. 1,) which is placed over the top of thepipes at such times.
